HENRY L. SOOFIELD, OF ROCHESTER, NEW YORK,'ASSIGNOR TO SCOFIELD BROTHERS, OF SAME PLACE.

LAST.

RPECIFICATION forming part of Letters Patent No. 352,893, dated November 16, 1886. Application filed February 27, 1896. Serial No. 193,515. (No model.)

"a full, clear, and exact description of the same,

reference being had to the drawings accompanying this application.

The object of my invention is twofold: first,

- to prevent the disengagement of the lastblock from the last when pounding on the latter; and, second, to enable the last-block to be withdrawn from the last endwise while the shoe is still on,- and without loosening the buttons.

To this end the invention consists of a socket secured in the body of the last, a headed pin resting in the socket, protruded outward by a coiled spring, and a bearing secured in the dast-bl'ock, provided with a hole, into which the bolt shoots when the block is fully closed, all as hereinafter described. Y

In the drawings, Figure 1 is a top view of a last,showing my improvement appliedthereto. Fig. 2 is a longitudinal vertical section of the same, with the last-block closed. in place and the parts locked together. Fig. 3 is a view similar to Fig. 2, but showing the last-block in theraised position and in the act of closing. Fig. 4 is a perspective view of the parts composing the fastening devices, shown detached.

A indicates the last, and B -the last-block, which are of ordinary construction.

My improvement is as follows:

C is a cylindrical socket, which is set into a hole bored in the body of the last near its top, and provided with a curved flange, a, that fits a cavity made in the face of the last where the block is cut out and secured by a screw, 1). The interior of this socket has a large cylindrical opening in the rear and a smaller one in front, with a square shoulder between them.

D is a cylindrical pinwith an enlarged circular head, the pin passing through the small opening in the front of the socket, and the head running in the enlarged opening in the rear.

E is a coiled spring, which rests in the socket behind the-pin. It will be Seen that the tendency of the spring is to protrude the pin outward through the socket and beyond the face of the last.

G is a triangular metallic block set into an opening formed in the inner face of the lastblock B, being secured by a screw, d. It has a hole,f, near'the top, which, when the block is fitted closely in place in the last, coincides or comes in line with the pinin the last, which pin shoots into it, and secures the parts together, as shown in Fig. 2. In this condition, when the shoe is on, the block, cannot be removed from the last except by forcing back the pin. To remove the last-block, the end of a curved hook, H, is inserted through the hole f, the pin is pushed back, when, by drawing on the hook without removing it, the block can be drawn out endwise, as indicated by dotted lines, Fig. 2, without unbuttoning the shoe on the last.

In ordinary lasts now in use the fastening is attached to the block and engages with the last. In pounding on the last in such case the tendency of the reaction under theconcussion is to force the catch back into the block and separate the parts; but by locating the pin in the last, as in my invention, the tendency is to force the pin forward and make it hold more securely in place. The most important advantage, however, is that by placing the pin in the last, and -carrying the hole f in the block clear through the block, the hook can be inserted on the outside to drive the pin back, and at the same time draw the block from the last without removing the hook. By this means it is not necessary to raise or remove the last-block from contact with its seat in the last, as in most devices of the kind, but it can be simply drawn out endwise, and as the diameter of the. block decreases downward the hold on the leather is gradually lessened as it is drawn out. Therefore theblock can be withdrawn without unbuttoning the shoe or straining the same. This construction is also such that the parts are self-locking by simply pressing the block down to place. This is illustrated in Fig. 3. As the block is pressed down it forces back the pin, and when in .place the pin and hole coincide.

the outside at the rear end of the block to press the pin back and withdraw the block, as herein shown and described.

In witness whereof I have hereunto signed my name in the presence of two subscribing I 5 witnesses. HENRY L. SCOFIELD.
